Platform etc details: * sdl versions and so on are still the same as the attachment to issue #111 indicates ( http://pulkomandy.tk/projects/GrafX2/attachment/ticket/111/47-54.png ) * Arch Linux x86_64; Linux 5.0.10-arch1-1-ARCH * Spectrwm window manager, v 3.2.0 running on Xorg 1.20.4 Other details: * Not sdl specific (I tested with API=x11 as well; same result) * The md5sum of the installed binary is the same as the one in the bin/ directory (so the binaries really are identical) * Does not depend on working directory... I *guess* this probably means it is dependent mainly on the particular path to the binary.. * Since gdb hides the problem, I'm not sure what else to try. Valgrind? A working barebones setup: ---- # start in the top level directory of the grafx2 git clone, and execute this. mkdir /tmp/g cp -a bin/grafx2_sdl /tmp/g mkdir -p /tmp/share/grafx2/skins cp -a share/grafx2/skins/*DPaint* /tmp/share/grafx2/skins /tmp/g/grafx_sdl # gfx2def.ini is not required, despite the error message. Copying it in to /tmp/share/grafx2 does not effect the result other than removing the error message. # the same applies to gfx2.png ---- It's curious that this particular snippet works, but hopefully the fact that it does work is informative somehow.
